Sway bars . best first mod.

 

Motordyne 5/16 spacer best bang for the Buck for added HP.

 

 

 

Since nothing I'm going to get will make a significant performance increase, I will probably do something to the exhaust, for a better sound. Like I said originally, I like the note of the stock exhaust, but would like it to be a bit louder. So do you think resonated test pipes would be worth it? I'm sticking with resonated because I want to stay clear of rasp if possible, and I think they'll work well with a stock-style aftermarket exhaust later on.

 

Astroglide?

 

if i had 06 350Z :
_ i have the best intake > only add drop in K&N filter.
_ exhausts all fart cans > stay stock only change the cats with Resonated TP or Berk HFC + MD XYZ straight pipe (keep 350Z beautiful sound only louder and no RASP "Tony from MD approved it").
_ 5/16 MD (the only real mod that u can feel in your butt dayno).
_ Valks or Axis 19" wheels (no 20" too much noise inside the car ,,,no spacers).

and i get another GF with bigger boob job lol
but its just me , and i`m working on it .

 

Sounds about what I was thinking. Does a K&N really flow that much better or should I just wait 'til I need to replace the filter? I think my first mod will be Topspeed resonated test pipes. Then Motordyne plenum spacer. If I like how the exhaust sounds, I'll probably leave it. Not sure how long I'm keeping to car, so I don't want to go crazy... Thanks for everyone's inputs. The boob job will be for her birthday, because then I'm getting something too

 

no need to rush for the filter its not that big deal .
AND IT`S GOING TO BE A REAL HAPPYBIRTHDAY TO YOU
all the best man ,enjoy it
